Re: New Super Dearman
I have the same Alto and can confirm it was manufactured in th 1950's for Dallas of London - the same people who introduced the Grafton used by Charlie Parker! In fact they share the same case. As far as I know the Super Dearman was manufactured in Eastern Europe and is a Conn copy. Note the Nail File G key. Mine is still in 1st class condition and plays very well probably because they were extremely well built so I think it would be worth renovating.
